Midway Atoll survey of avian malaria prevalence in passerines 2023

Non-native passerines, common canary (Serinus canaria; n=24) and the common myna (Acridotheres tristis; n=19), were captured by US Fish and Wildlife Service Biologists on Sand Island, Midway Atoll, and had a blood sample taken to test for avian malaria (Plasmodium relictum) infection. Blood samples were analyzed for the presence of avian malaria DNA using a Realtime PCR (qPCR) assay. No evidence o

Kīpahulu Valley, Haleakalā National Park, Maui Seasonal Distribution and Relative Abundance of the Mosquito Culex quinquefasciatus, 2022-2023

This USGS data release consists of six data sets and accompanying metadata for a year-long study on the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, critical habitat for two endangered Maui endemic forest birds. Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum, a key limi

Guam, Andersen Air Force Base housing area visual surveys for brown treesnakes (Boiga irregularis) and associated tree data, December 2019–November 2022.

This data was collected as part of a larger project to examine predator-prey interactions between invasive Brown Treesnakes (Boiga irregularis, predator) and native prey species at a study site located in a peri-urban area of Andersen Air Force base in Guam, USA. This dataset includes two datasets. One dataset contains 22 columns and includes data collected on Brown Treesnakes captured between 23

Hawaiian Islands habitat suitability models for highly invasive plants based on global and regional data for baseline climate scenario (1990-2009)

We created a comprehensive estimate of potential distribution for a subset of 17 ecosystem modifying invasive plants (EMIPs) in Hawaiʻi. This work uses methods that integrate a wide set of data sources including agency and citizen science data, but perhaps more importantly, the integration of regional and global distribution information for these species. We built three sets of ensemble species di

Kaloko-Honokōhau National Historical Park shrimp density and anchialine pool characteristics, 2017

This data release includes metadata and tabular data that documents counts of shrimp and measurements of field variables aimed to identify factors that affect the distribution and abundance of the uncommon anchialine pool shrimp Metabetaeus lohena at Kaloko-Honokōhau National Historical Park during 2017. The data set documents biological, chemical and physical attributes within 173 anchialine pool

Guam, Morphometric and height data for brown treesnakes were detected at four sites on Guam, 2006 - 2023

These data were collected as part of several studies or efforts to remove brown treesnakes (Boiga irregularis) across three sites located in Guam, USA and one site in Cocos Island (Dano), Guam, USA. The various goals of projects were distinct and these data were applied to a more intensive, cross site comparison on the height snakes were detected during visual surveys as a function of their size o

Guam, Post-storm Mariana swiftlet colony size and nest counts, 2023

The Yǻyaguak (Mariana Swiftlet; Aerodramus bartschi) is an endangered cave-roosting species native to Guam and southern Mariana Islands, Micronesia. On May 24-25, 2023, Guam was hit by the category-4 Typhoon Mawar, which brought wide-spread destruction to the island. Approximately 6 weeks prior to the typhoon in April 2023 we conducted surveys of the three known colonies of Yǻyaguak at Mahlac, Mae

First and Second Record of US-RIIS Vascular Plant Species in Contiguous United States

This is a dataset containing the first and second record of georeferenced observations of introduced and invasive vascular plant species in the contiguous United States (CONUS). Non-native plant species were identified using the United States Register of Introduced and Invasive Species (US-RIIS) list. After identifying a list of plants non-native to CONUS, we obtained presence data from aggregated

Island of Hawaiʻi lidar-based habitat suitability for ʻākohekohe (Palmeria dolei) conservation introductions, 2023

This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat suitability

Samoan swallowtail butterfly reproductive life history and parasitism, 2013-2014

This data release includes metadata and tabular data documenting the reproductive demography of the Samoan swallowtail butterfly (Papilio godeffroyi), including rates of parasitism by two species of Ooencyrtus wasp. Data was collected at approximately monthly surveys of marked host trees (Micromelum minutum) at eight forest stands, mostly in or adjacent to the National Park of American Samoa (NPSA

Guam, USGS Closed Population (NWFN) data relating to brown treesnake and prey interactions processed into monthly intervals from 10/2016 - 2/2023

These data represent brown treesnake (Boiga irregularis) captures from a population in a 5 ha natural snake enclosure on Guam from 2016 - 2023. During the period of study we artificially reduced the number of snakes present in the population through a variety of control tools that included toxic baits, as mice and chicks, live trapping, and hand capture. We censused the population intensively duri

Guam, Mariana swiftlet counts, 2019-2023

The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). Population status assessments have, however, been challenging due to the limitations of traditional counting methods, whic
